American countries' militatia for identification (made by "Meyer")

[russiamilitaria]

Hello!

I've some badges, collar and boards insignia, etc., which were made by US company "Meyer". I suppose that they were produced for countries of Central and South America. I need help with their identification of counry's accessory and time of existence.

Thanks.
